' COAL SEPARATOR 7 Filed Aug. 15. 1928 2 Sheet-Sheet 2 Attorney Patented ea. 30, 1930 PATENT OFFICE narrate TARONE AND JOHN RowLANnoFRAvnnnuN, PENNSYLVANIA COAL SEPARATOR,

Application filed August 15,-1928/ Serial No. 299,668.

The presentinvention relates to improvements in coal separators and has reference more particularly to certain improvements over the separator disclosed in our'copending 5 application bearing-Serial No. 276,139'1'iled May 8, 1928. v

-Oi1e of the important objects of the pres ent invention isto provide a separator for separating slate,-dirt, cone and't-he like from coal. I

I One of the importantobjects or" the present invention is to provide a'coal separator which includes upper and lower inclined chutes, each of which is hingedly secured at its upper end to the supporting structure, means being associated with the lower end of each chute I pensive, strong and durable and-further well adapted to the purposes for WlliClilt 15 designed. c.

Other objects and advantages will become apparent during the course ofthe'following description.

. In the accompanying drawing, t'orming a part of this specification, and in which like numerals indicate like'parts throughout the same: c Figure 1 is a side elevation of the coal separator embodying our invention, v

Figure 2 is a fragmentary view showing the upper chute in section and its association with the supporting'structure, and

- Figure 3 is a detail perspective view of one of the inclinedchutes, the retarding or checking unit being removed therefrom.

- In the drawings wherein for the purpose oi ment of our invention nuineral'1 designates enerallv a sup ortin structure that consists v n b of a frame work. 7

An inclined chute?) is positioned in the upper portion of the supporting structure 1 acter which is simple in construction, lIlQX- r illustration-is shown the preferred elnbodt 1 Figures 1 and 2. r

chute 4 associated therewith for delivering the coal with itsimpurities to the uppermost inclined chute 5 forming a part of our present invention. v

This upper chute 5 is formed along its longitudinal side edges with the upstanding side flanges 6 while the intermediate portion of the chute '5 is formed with a transverse enlarged opening 7. I v c The upper longitudinal edge of the open ing 7"is slightly curved upwardly as at 8 while the other longitudinaledge portion of the opening 7 is directed downwardly to provide a deflecting lip 9 the purpose of which will be hereinafter more fully described.

The upper chute 5 is hingedly connected at its upper edge to a suitable cross bar 10 as at 11. that is arranged directly below the chute t as clearly suggested] in Figure 2 of the drawings and for the purpose of raising and lowering the lower end portion of the upperchute 5, there is provided a flexible cable 12, the lower endfof which is forked and con nected to the forward or lower end portions or the r upstanding sides 6 as shown in 80 Figure 3. v a

The other end of the cable is trained over asuitable pulley 13'supported in the supporting structure .1 and is connected to apivoted leverf14= also mounted on the supporting I structure and a suitable pull and ratchet mechanism such as shown generally'at 15 may be asseciated wit-h the lever '14 and the sup-v porting structure for maintaining the hinged p pper chute 5 at any angularly'inclined'posi t ion. 1 1

An angularly disposed retarding or checking unit inthe form of a plate 16 is fixedly attached to the upper end portion ofth chute 5 for disposit-ionforwardly of the chute 4 and suitable supporting links 17 are provided for this plate like retarder 16 as clearly shown in A lower inclined chute 18 which is identi- TN cal 1n construction with the upper inclined .chute is hingedly secured at its upper end in the supporting structure 1 for disposition directly below the lower end of the upper chute 5 and the same means is associated with the lower end of the lower chute 18 for raising and lowering the same as is provided for association with the lower endot the upper chute 5 and this elevatingmeans is denoted generally by the referencecharacter lQ. I

A retarding or checking unit 20 which is also of the same construction as the retarding or check unit 16 is associated with the lower inclined chute 18'tor disposition at'the upper hinged end of thelower chute 18.1 I

Transversely extending inclined boxes or troughs 21 and 22 are disposed for disposition beneath the transverse opening iormed 1n the 7 upper and lower inclined chutes respectively chute '5 and the same will by gravity pass downwardly in said chute, the lumpsof coal jumping the space 7 and continuing downwardly on the chute 5 while the dirt, slate and other impurities will pass through the opening '7, and there will be deflected into the trough by means of a lip-9.

I The coal upon leaving the upper chute-'51 will strike the retarding unit 20 and will be caused to flew up; in its travel downwardly in the lower chute 18 and the same action will take place in the lower chute so that any impurities that may accidentally pass along with the coal from the upper chute 5 to the lower chute 18 will be removed through the 1 opening in the lower chute 18 and discharged into the transverse trough 22.

Finally the coaltree of its impurities will enter the chute 24 and will be carried oif to any suitable point.

It will thus be seen from the f oregoing description, that we have provideda coal separator that includes certain improve- .mentsover the separator disclosed in our 00- :pending application and by raising and lowringthe h nged:incl ne 'cl t i t pe d at which the coal travels downwardly through t e separ r may be regula ed- Whi e we hav howuth pr te redem:

stood thatvarieu chan es in thesiz i hapep n arrangemen o part be eserted' o H ngthus/ es r b d ur inve tie ,;wha

In a coal separator, a supporting struc ture, a plurality of inclined chutes hingeclly connected at their upper ends to the supporting structure, means at the lower ends of the chute for vertically adjusting the same,

the upper ends of the inclined chute underv lying the lower ends of the uppermost chute,

a retarding chute extending laterally and upwardly from the upper portion of each of the aforementioned chutes for deflecting the material for the next -nppe1'most chute against the chute to which the retarding unit is attached, said retarding chutes being oppositely inclined from the supporting chutes and rigidly secured thereon and further having their lower ends communicating with the supporting chutes in spaced relation thereto,

each otthe hingedly mounted chutes being formed in its bottom with an opening through which the impurities of the coal pass, the upper longitudinal edge of the opening being slightlycurved upwardly, a downwardly extending deflecting lip formed on V the opposite longitudinal edge of each opening, and an inclined trough for disposition beneath each, of the openings.

In testimony whereof we affiX our signatures. I
